Two-Dimensional Attosecond Electron Wave Packet Interferometry

Abstract

We propose a two-dimensional interferometry based on electron wave packet interference with a cycle-shaped orthogonally polarized two-color laser field. With such method, sub-cycle and inter-cycle interferences can be disentangled into different direction in the measured photoelectron momentum spectra. With the cycle-shaped laser field, the Coulomb influence can be minimized and the overlapping of interference fringes with the complicate low-energy structures can be avoided as well. The contributions of excitation effect and long-range Coulomb potential can be traced in the Fourier domain of the photoelectron distributions. With these advantages, it allows to get precise information on valence electron dynamics of atoms or molecules with attosecond resolution and additional spatial information with angstrom resolution.
